Removing MDM profile from an iPad that I have legally purchased
The IT departement of my school has installed the MDM profile of their server on my iPad. So, my iPad is now under the IT departement control. But the iPad is mine, I have bought my iPad last year with my money, and i have the invoice.
How can i remove the MDM profile on this iPad that i have legally purchased? Can an Apple Store Genius Bar do this operation?
The IT departement has also the serial number of my iPad; so, if the Apple Store remove my iPad from my school MDM, will the it departement be able to add another time my iPad?
iPad Air, iOS 9.3.2
